This research aims to develop a highly efficient catalyst for the oxidation of toluene, a toxic volatile organic compound.
Fabricated porous TiO2/SiO2 support via titanium pillaring of montmorillonite.
Calcined and acid-leached the support to prepare Pt-TiO2/SiO2 catalysts.
Evaluated catalyst performance under varying conditions including water vapor.
Monitored catalytic mechanism using in situ DRIFTS.
0.37 wt.% Pt catalyst demonstrated superior toluene oxidation, achieving a T90 of 190°C.
Catalyst maintained high activity and stability despite 10% water vapor.
No significant deactivation was observed after 48 hours of continuous operation.
Catalytic mechanism involved transformation of toluene into multiple intermediates, ultimately mineralizing into CO2 and H2O.
